Application September 12, 1940, Serial No. 356,534 2 Claims. (Cl.139-402) This invention relates to a rug, and more particularly to atype of rug in which the upper body is formed by long, uncut, twistedloops. l

A rug having long, twisted loops extending thereabove and providing apleasing appearance,

the long, twisted loops resembling what is known as bullion fringe, ha'slong been in demand. By reason of the length of the twisted loops, ithasalways been felt necessary to form thloops separately and stitch them toa woven fabric base, a laborious and expensive operation. No one, hasattempted to form the long, twisted loops from integral portions of thewoven rug because of the tendency of the loops, when formed in themanner in which cut, short-pile rugs are formed, to strip or pull out,forming unsightly threads.

I have discovered that by modifying the weaving operation, that abullion twist rug can be formed integrally with the rug body, providinga sturdy and attractive product more pleasing in appearance than therugs of this type heretov fore formed.

An object of the invention is to provide a bullion twist form of rug inwhich the long loops are formed integrally with the rug body, amodicationof the weaving operation being employed for securely lockingthe loops against being pulled out of place. Other specific objects andadvantages will appear as the specification proceeds.

The invention is illustrated, in a preferred embodiment, by theaccompanying drawing, in which- Figure 1 is a broken top plan view of afragment of the rug embodying my invention, some of the loops being outoi near their bases; and Fig. 2, a greatly enlarged sectional View, thesection being taken as indicated at line 2 of Fig. l.

In the practice of my invention, I prefer to employ -two kinds of warpthreads, namely pile warp and ground warp, and one kind of weft orfilling thread. In the drawing, the weft threads are indicated in seriesof ves by the numerals I to 5 inclusive, while the ground warpthreadsare indicated by the numeral lll. The pile warp is indicated by thenumeral Il, and the twisted loops by the numeral I2.

The weft or filling threads l to 5 inclusive, as well as the ground warpthreads I0, are preferably tightly twisted to form a sturdy tight-bodyfor gripping the pile warp. The pile warp in the illustration given is atwo-ply structure, each ply being first slack-twisted and then broughttogether and over-twisted. The over-'twist substantially takes out theslack-twist in the individual plies, and the resulting twisted Warpthread is bulky in appearance and relatively soft. Such pile warp ll istightly gripped between the -closely drawn weft threads and groundthreads and securely held in position where at least ve weft threads areemployed between each loop. By employing long loops which extend wellbeyond the space between loops and by spacing the loopsv closelytogether in a lateral direction, that is, in the direction of the weftthreads, I provide a pile body which completely covers the underbodystructure, giving a very attractive appearance while at the same timeproviding loops which will not be drawn from the rug body in the use ofthe rug. Because of the short pile heretofore used in the making ofrugs, it has been customary to employ only a vfew weft threads betweeneach row of loops, and with such a structure it was impossible to employlong, twisted loops of the type now shown. However. in the practice ofmy invention where long loops are employed tending to bridge over andcover the spaces between the rows of loops, it is p'ossible to use atleast ve weft threads between each row of loops and thus securely lockthe threads against drawing. The softeness or the loosely-wovencharacter of the warp threads not only provide a more attractive rugfrom the standpoint of appearance, but also cooperate with thetightly-drawn and twisted weft and ground threads for locking the pilewarp against longitudinal movement under strain. While the large numberof weft threads between the rows of loops has heretofore seemedprohibitive by reason of the open space left, I find that the long loopsemployed more than cover such surface and conceal it sufciently torenderv the rug attractive in appearance. It will be understood thatseven weft threads between rows and a larger number of weft threadsbetween the spaced rows result in an extremely attractive and sturdyrug. With less than five rows, I find that a usable and workable rugcannot be produced.

By means of the above rather simple steps,

' I find that it is no longer necessary to stitch the individual loopsto a woven fabric body and that,

instead, a very sturdy rug which will stand up.

under the use to which rugs are put, can be produced much more cheaplyand with less loss than such former rugs while at the same time havingthe entire rug integral. The rug can be launderedand passed through awringer without' injury thereto and without distortion of the loopsforming the upper portion of the rug body.

While in the foregoing description, I have set forth certain details. itwill be understood that such details arev given for the purpose ofillus-V tration only and that it will be obvious to men skilledin theart that changes in such details may be made without departing from thespirit of my invention.

I claim:

1. A rug of the class set forth, consisting essentially of ground andpile warp threads interwoven with weft threads, the pile warp threadsbeing formed of over-twisted ply-yam, each of the plies of which isslack twisted, each of the pile warp threads being spaced apart from thenext adjacent pile warp threads by a pair of ground warp threads, one ofsaid pair ofground warp threads being in the same shed with the pilewarp threads whereby the weft threads pass on the same side of the pilewarp thread and one of the ground warp threads and on the opposite sideof the other of the pair of ground warp threads, the pile warp threadsat spaced intervals being drawn from the woven fabric to form longspirally twisted loops constituting the upper body of the rug, the loopsbeing of greater length than the distance by which they are spacedapart, each loop being drawn upwardly between two next adjacent weftthreads, one of said pair of ground warp threads passing over said twoweft threads.

2. A rug of the class set forth. consisting essentially oi ground andpile warp threads tightly interwoven with weft threads, the pile warpthreads having a relatively high twist and being soft and bulky and thewett and ground warp threads being tightly twisted and relatively hard.each oi' the pile warp threads being spaced apart from the next adjacentpile warp threads by a pair of ground warp threads, one of said pair ofground warp threads being in the same shed with the pile warp threadswhereby the weft threads pass on the same side of the pile warp threadand one of the ground warp threads and on the opposite side of the otherof the pair o! ground warp threads, the pile warp threads atspacedintervals being drawn from the woven fabric to form long spirallytwisted loops constituting the upper -body of ,the rug, the loops beingspaced apart by not more than tive weit threads and being of a greaterlength than the distance by which'vthey are spaced apart, each of theloops being drawn upwardly between two next adjacent weft threads, oneoi said pair ot ground warp threads passing over said two weft threads.A
